摘要： A vehicle control system comprises an industry standard CAN network with a number of nodes distributed around the vehicle for controlling corresponding parts of the vehicle. One such node is located in the housing of the vehicle interior rearview mirror and directly controls the reflectivity of an electro-optic mirror unit, in accordance with the state of at least one ambient light sensor and a remote keyless entry device. The node also communicates via an ISO9141 interface with a number of slave controllers such as a sun-roof control module mounted adjacent a sun-roof and a roof control module mounted in a roof housing. By this means the UCM exercises indirect control of the sun-roof in accordance with the state of a switch, and exercises indirect control of various lamps GEN1, GEN2, FLL and FRL in the roof housing in accordance with the state of switches Gen, FL and FR mounted in the roof housing or, in the case of the lamps GEN1 and GEN2, when a vehicle door is opened.

摘要： An electronic compass is described for use in vehicles. The compass employs a magnetoresistive sensor for sensing the earth magnetic field and the sensor is operated in alternate set/reset bias modes. In a first embodiment, the compass is provided with deviation compensation by a closed loop system including measurement of the sensor output signals and an offset current strap for nullifying the vehicle deviation field. In a second embodiment, deviation compensation is provided by operation in an initial calibration mode and by operation in a normal compensation mode to adjust compensation, as needed, on a long term basis during normal operation of the compass. In the initial calibration mode, while the vehicle is being driven, the signal peak values are adjusted to a nominal earth field level by changing the offset current. Then, compensating signal reference values for each axis are determined as each peak for that axis is determined. The system automatically exits the initial calibration mode when certain criteria have been met. In the normal compensation mode, the signal reference value for each axis is adjusted at least once during the time interval between turn-on and turn-off of the vehicle ignition switch.

摘要： A control for a moisture sensing assembly, adapted for mounting on the inner surface of a vehicle window or windshield to control vehicle accessories such as windshield wipers, maximizes the window area being sensed in relationship to the size of the assembly and provides immunity to interference from environmental influences. In the preferred embodiment, moisture on the outer window surface is detected by first and second moisture sensors each including infrared energy radiating diodes and radiant energy detectors which detect and process radiant energy to produce a moisture signal that is a function of the moisture on the window. A synchronizing circuit intermittently actuates the radiating diode for the two sensors individually and alternatingly at equally-spaced intervals. The synchronizing circuit also inhibits the radiant energy detectors from processing the radiant energy signal except when the corresponding radiating diodes are emitting energy in order to prevent interference from the other radiating diodes and environmental influences. The synchronizing circuit includes a pair of oscillators which include capacitors and coupling devices that coordinate the discharging of the capacitors in a manner which provides equal intervals between alternating output pulses from the oscillators.

摘要： A compass and method of operation are disclosed for finding the heading of a vehicle. The heading is found using a compass having a rotor with a compass magnet thereon and means on the rotor defining a reference line in known relation with the polar axis of the magnet. The angular displacement of the rotor is measured between alignment with the direction reference axis and alignment with the local magnetic field. A search coil is used to torque the rotor so that it reaches a reference position in which the reference line thereon is aligned with the direction reference axis. A reference position encoder generates a pulse when alignment is achieved. An angular displacement encoder produces a digital signal which changes with each predetermined increment of rotation of the rotor and which is indicative of the direction of rotation. A microcomputer processes the signals to provide a cumulative count of the increments of rotation. The microcomputer adds a stored magnetic variation value to the cumulative count to provide an indication of true heading. A direction display is adapted to exhibit one direction symbol of a set of symbols for different vehicle headings with each symbol corresponding to a different range of counts in the cumulative count. The microcomputer converts the cumulative count to a different direction value for each different range and the display is changed when there is a change of direction value. The microcomputer provides a logical hysteresis to prevent the display from flashing between different symbols when the cumulative count is at a marginal value of a given range. The microcomputer also provides a time damping of the display by imposing a time delay before changing the display from one symbol to another.

摘要： A compass compensation system is provided for automatically and continuously calibrating an electronic compass for a vehicle, without requiring an initial manual calibration or preset of the vehicle magnetic signature. The system initially adjusts a two axis sensor of the compass in response to a sampling of at least one initial data point. The system further calibrates the compass by sampling data points that are substantially opposite to one another on a plot of a magnetic field and averaging an ordinate of the data points to determine a respective zero value for the Earth magnetic field. The system also identifies a change in magnetic signature and adjusts the sensor assembly.

摘要： An adaptive light-responsive vehicle control, such as an electro-optic rearview mirror system, and a method of adapting a light-responsive vehicle control to a vehicle which accommodates variations in vehicle configuration includes providing at least one light sensor receiving light passing through the vehicle rear window and monitoring this light sensor, such as for an extended period of time. At least one operating parameter, such as sensitivity, of the light-responsive vehicle control is established as a result of the monitoring. This allows the same light-responsive vehicle control to be used with both tinted and non-tinted rear windows.
